NVM Express Inc. announced today that it is initiating an effort to specify a standard for NVM Express (NVMe) over Fabrics. NVMe over Fabrics will extend the benefits of NVMe to where usage over fabric is more appropriate than using PCIe. NVM Express also announced a revision of version 1.2 of its NVM Express Specification.

NVM Express also announced a revision of version 1.2 of its NVM Express Specification.
NVM Express is a scalable host controller interface designed for enterprise, data center, and client systems. NVMe has been utilizing PCIe interface based on SSDs. With NVMe over Fabrics will enable end-users to achieve faster application response times and better scalability across virtual data centers by connecting remote subsystems with flash appliances. Though this ability already exists, using NVMe end-to-end eliminates the increased latency through SCSI translation. End-users will see similar latency regardless if the SSDs are remote or local. NVMe over Fabric is aimed at flash appliances that use fabrics such as Ethernet with RDMA, InfiniBand, and Intel Omni Scale Fabric.
NVM Express Specification 1.2
NVM Express Specification is the standard for enterprise and client non-volatile memory based storage solutions, such as PCIe SSDs. The new version adds features for both enterprise and client systems such as:
- For Enterprise:
- Enhanced status reporting
- Expanded capabilities including live firmware updates
- For Client systems:
- Better power management
- More mobile-oriented capabilities
- Enable SSDs with low to no DRAM
Availability
NVMe over Fabrics is still in the prototype stage and will be demonstrated at the Intel Developers Forum, September 9-11.
The NVM Express Specification 1.2 will be available for download in the fourth quarter of 2014.
